The font-harmattan from silnrsi

Harmattan latin glyphs are not the same size as Andika

Harmattan reuses Andika glyphs, which is nice, but it also resizes them.
The end result is writing documents that mix Harmattan and Andika (because Andika has progressed since its import in Harmattan) is challenging.

Please keep the sizing of the common latin glyphs in all sil fonts coordinated.

FTML files missing required <head> element

The FTML spec states that the element is a required element of a file and is missing from a number of .ftml files in tests/

GF update : review

Hello :)
This a Fontbakery report for Harmattan + a report to compare the font already on Google and the update.
You can look into this, try to resolve some fail, although if you have questions about how to resolve them or which one to ignore according to this project (example with the vertical metrics, but it is about to be figured out here). Any case, we can organise a quick call to clear things out.

🔥 FAIL: Check `Google Fonts Latin Core` glyph coverage.

com.google.fonts/check/glyph_coverage

--- Rationale ---

Google Fonts expects that fonts in its collection support at least the minimal
set of characters defined in the `GF-latin-core` glyph-set.

🔥 FAIL Missing required codepoints: 0x2074 (SUPERSCRIPT FOUR) and 0x2215 (DIVISION SLASH) [code: missing-codepoints]

🔥 FAIL: Check license file has good copyright string.

com.google.fonts/check/license/OFL_copyright

--- Rationale ---

An OFL.txt file's first line should be the font copyright e.g:
"Copyright 2019 The Montserrat Project Authors
(https://github.com/julietaula/montserrat)"

🔥 FAIL First line in license file does not match expected format: "copyright (c) 2007-2008, the c&ma guinea fulbe team;"

🔥 FAIL: Check copyright namerecords match license file.

com.google.fonts/check/name/license

--- Rationale ---

A known licensing description must be provided in the NameID 14 (LICENSE
DESCRIPTION) entries of the name table.

The source of truth for this check (to determine which license is in use) is a
file placed side-by-side to your font project including the licensing terms.

Depending on the chosen license, one of the following string snippets is
expected to be found on the NameID 13 (LICENSE DESCRIPTION) entries of the name
table:
- "This Font Software is licensed under the SIL Open Font License, Version 1.1.
This license is available with a FAQ at: https://scripts.sil.org/OFL"
- "Licensed under the Apache License, Version 2.0"
- "Licensed under the Ubuntu Font Licence 1.0."


Currently accepted licenses are Apache or Open Font License.
For a small set of legacy families the Ubuntu Font License may be acceptable as
well.

When in doubt, please choose OFL for new font projects.

🔥 FAIL License file OFL.txt exists but NameID 13 (LICENSE DESCRIPTION) value on platform 3 (WINDOWS) is not specified for that. Value was: "Copyright (c) 2007-2008, The C&MA Guinea Fulbe Team;

SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others.

The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.

DEFINITIONS
"Font Software" refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. This may include source files, build scripts and documentation.

"Reserved Font Name" refers to any names specified as such after the copyright statement(s).

"Original Version" refers to the collection of Font Software components as distributed by the Copyright Holder(s).

"Modified Version" refers to any derivative made by adding to, deleting, or substituting -- in part or in whole -- any of the components of the Original Version, by changing formats or by porting the Font Software to a new environment.

"Author" refers to any designer, engineer, programmer, technical writer or other person who contributed to the Font Software.

PERMISSION & CONDITIONS

🔥 FAIL: Is the Grid-fitting and Scan-conversion Procedure ('gasp') table set to optimize rendering?

com.google.fonts/check/gasp

--- Rationale ---

Traditionally version 0 'gasp' tables were set so that font sizes below 8 ppem
had no grid fitting but did have antialiasing. From 9-16 ppem, just grid
fitting. And fonts above 17ppem had both antialiasing and grid fitting toggled
on. The use of accelerated graphics cards and higher resolution screens make
this approach obsolete. Microsoft's DirectWrite pushed this even further with
much improved rendering built into the OS and apps.

In this scenario it makes sense to simply toggle all 4 flags ON for all font
sizes.

🔥 FAIL Font is missing the 'gasp' table. Try exporting the font with autohinting enabled.
If you are dealing with an unhinted font, it can be fixed by running the fonts through the command 'gftools fix-nonhinting'
GFTools is available at https://pypi.org/project/gftools/ [code: lacks-gasp]

🔥 FAIL: Copyright notices match canonical pattern in fonts

com.google.fonts/check/font_copyright
🔥 FAIL Name Table entry: Copyright notices should match a pattern similar to: "Copyright 2019 The Familyname Project Authors (git url)"
But instead we have got:

🔥 FAIL: Font enables smart dropout control in "prep" table instructions?

com.google.fonts/check/smart_dropout

--- Rationale ---

This setup is meant to ensure consistent rendering quality for fonts across all
devices (with different rendering/hinting capabilities).

Below is the snippet of instructions we expect to see in the fonts:
B8 01 FF    PUSHW 0x01FF
85          SCANCTRL (unconditinally turn on
                      dropout control mode)
B0 04       PUSHB 0x04
8D          SCANTYPE (enable smart dropout control)

"Smart dropout control" means activating rules 1, 2 and 5:
Rule 1: If a pixel's center falls within the glyph outline,
        that pixel is turned on.
Rule 2: If a contour falls exactly on a pixel's center,
        that pixel is turned on.
Rule 5: If a scan line between two adjacent pixel centers
        (either vertical or horizontal) is intersected
        by both an on-Transition contour and an off-Transition
        contour and neither of the pixels was already turned on
        by rules 1 and 2, turn on the pixel which is closer to
        the midpoint between the on-Transition contour and
        off-Transition contour. This is "Smart" dropout control.

For more detailed info (such as other rules not enabled in this snippet),
please refer to the TrueType Instruction Set documentation.

🔥 FAIL The 'prep' table does not contain TrueType instructions enabling smart dropout control. To fix, export the font with autohinting enabled, or run ttfautohint on the font, or run the gftools fix-nonhinting script. [code: lacks-smart-dropout]

🔥 FAIL: Are there caret positions declared for every ligature?

com.google.fonts/check/ligature_carets

--- Rationale ---

All ligatures in a font must have corresponding caret (text cursor) positions
defined in the GDEF table, otherwhise, users may experience issues with caret
rendering.

🔥 FAIL Failed to lookup ligatures. This font file seems to be malformed. For more info, read: fonttools/fontbakery#1596 [code: malformed]

🔥 FAIL: Name table entries should not contain line-breaks.

com.google.fonts/check/name/line_breaks

--- Rationale ---

There are some entries on the name table that may include more than one line of
text. The Google Fonts team, though, prefers to keep the name table entries
short and simple without line breaks.

For instance, some designers like to include the full text of a font license in
the "copyright notice" entry, but for the GFonts collection this entry should
only mention year, author and other basic info in a manner enforced by
com.google.fonts/check/font_copyright

🔥 FAIL Name entry COPYRIGHT_NOTICE on platform WINDOWS contains a line-break. [code: line-break]
🔥 FAIL Name entry LICENSE_DESCRIPTION on platform WINDOWS contains a line-break. [code: line-break]

🔥 FAIL: Name table strings must not contain the string 'Reserved Font Name'.

com.google.fonts/check/name/rfn

--- Rationale ---

Some designers adopt the "Reserved Font Name" clause of the OFL license. This
means that the original author reserves the rights to the family name and other
people can only distribute modified versions using a different family name.

Google Fonts published updates to the fonts in the collection in order to fix
issues and/or implement further improvements to the fonts. It is important to
keep the family name so that users of the webfonts can benefit from the
updates. Since it would forbid such usage scenario, all families in the GFonts
collection are required to not adopt the RFN clause.

This check ensures "Reserved Font Name" is not mentioned in the name table.
